Abstract: 1290971 Spatial filtering ENTREPRISE DE RECHERCHES ET C'ACTIVITIES PETROLIERES 2 June 1970 [10 June 1969] 26619/70 Heading G2J [Also in Division H4) Information, e.g. seismic data, is optically processed by illuminating a transparency 16 containing the information with a parallel beam of coherent mono-chromatic light, forming a power spectrum of the transparency in the Fourier transform plane 17 of a lens 7 and locating in said plane 17 a filter consisting of a screen having a transparency which varies over its surface as the auto-cavelation function of the spectrum of the transparency 16, and reconstituting the filtered image 25 of the transparency. In one embodiment the Fourier transform plane 17 is associated with a single spherical transform lens 7 and a spherical reconstituting lens 8. In an alternative embodiment both the transform and reconstituting lens systems 7, 8 comprise a spherical lens 26 or 28 and a cylindrical lens 27 or 29. The image focal planes of lenses 26, 27 coincide in the transform plane 17. The generatrices of cylindrical lenses 27, 29 are vertical and disposed parallel, e.g. to bands on the transparency. Thus the Fourier transform is formed as a series of vertical straight line spectra. The filter is formed as follows: The transparency is placed in the object plane of lens 7 and the spectrum formed in the transform plane is photographed to record the first order power spectrum; this photograph is then placed in the object plane of lens 7 and the process repeated to get a second order power spectrum record; Using this second record the process is again repeated to obtain a positive third order power spectrum record the transparency of which varies as the auto-correlation function of the first order spectrum. In the first and second operations to form the filter the photographic record produced, which is a positive, is reversed in polarity, that is a photographic plate is printed in contact with the film, to give a negative. The positive filter obtained is used to non-periodic random elements from the information in the transparency. If this filter is made as a negative it filters out periodic elements.

Abstract: 1304187 Jointing timber WADKIN Ltd 11 Nov 1970 [12 Nov 1969(2)] 55361/69 and 55363/69 Heading B5L A method of connecting two timber pieces 16, Fig. 5, by a finger joint comprises positioning the pieces in end to end alignment with a space between them, placing in the space, a movable double-faced finger forming die 2 with the finger-forming faces directed towards the ends of the pieces 16, and whilst holding one piece stationary, moving the other piece towards it so as to engage the die and move it against the stationary piece and impress the die into the ends of both timber pieces. In apparatus for performing the method the die 59, Fig. 4, is pivoted on a shaft 12 mounted in one arm 41 of a rotatable carrier 34. The other arms 38, 39, 40 of the carrier bear adjustable spacing wedges 46, trimming knives 47 and glue applying rollers or brushes 49 respectively. The carrier 34 is mounted on a shaft 35 positioned so that on rotation its arms can be brought in turn to a position between the ends of timber pieces T2, T1, Fig. 9, on a fixed table 121 and a movable table 13 respectively. A bell crank lever 19 moves the table 13 and is controlled by a cam 22 on a shaft 23. The drive for shaft 23 is geared to a drive for discs 56 via a pin-wheel 52 cause intermittent rotation of the carrier 34. In operation of the apparatus timber pieces are fed by rollers over table 13 and the leading piece is fed more quickly by further rollers over table 121. When the trailing edge of the leading piece T2 is correctly positioned it operates a trip mechanism which stops the feed rollers of table 121 and operates a clamp 60 on that table. Similarly the piece T1 is clamped to table 13 on detection of its leading edge. The carrier 34 is then rotated to cause the wedges 46 to accurately position the timber pieces, the knives 47 to trim the ends of the pieces, and the die 59 to be placed between the ends whereupon the carrier is halted. A lobe 22<SP>1</SP> on the cam 22 then causes the table 13 to advance to cause the piece T1 to engage the die and move it against the piece T2 thus forming fingers in both pieces. The table 13 is then withdrawn and a pneumatic cylinder arrangement 43, Fig. 5, operates to release the die from the piece T2. The carrier 34 is again rotated to remove the die and cause glue to be applied to the fingers of pieces T1, T2 by the rollers or brushes 49. The table 13 is again advanced by cam 22<SP>11</SP> on the cam 22 to cause the fingers of the pieces tointerengage. The jointed timber pieces are then fed from the apparatus. In an alternative embodiment the die 59, and tools 46, 47, 49 may be mounted on a slidable carrier the die being slidable relative to the carrier in this case. The die may be a solid block or consist of a plurality of plates. Reference has been directed by the Comptroller to Specification 1,156,144.

Abstract: 1312616 Wire or rod terisioners CHRISTIANI & NIELSEN Ltd 3 June 1970 [31 July 1969] 38551/69 Addition to 1191533 Heading F2G In a stressing device of the kind claimed in claim 1 of Specification 1,191,533, the mould end of the block 18 is modified by the provision of a plurality of spaced bores 118 aligned in the axial direction, the bores allowing passage of a reinforcing element or elements from a mould portion 24 to the tensioning device 21, 22, a piston 119 being slidable axially in a central axial cylinder in the block portion 18, and an element 141 (being fast with the piston 119) having holes 142 bored therein in register with the bores 118. In one embodiment (Fig. 1) the upper end of the axial cylinder is plugged with a screwed plug 131 and sealed by rings 132. A neck portion of the piston projects through a   narrowed port 137 of the cylinder and defines a chamber 144. Elements to be tensioned are locked into member 21 with collets in the tapered ends of bores 20, and the tensioning element removed upwards away from plug 131. When tight, pressure fluid admitted via channel 133 forces piston 119 and plate 141 downwards to press collets (not shown) into the tapered ends 149 of bores 136 in the mould. Introduction of pressure fluid via channel 148 raises the piston to abut plug 131, and the tensioning member 21, 22 may be lowered to repeat the operation. In a second embodiment (Fig. 2, not shown) the central axial cylinder does not extend as far as element 21, thus obviating the necessity of plug 131, the narrowed portion 137 being replaced by a ring (151) screwed into the lower end of the cylinder.

Abstract: 1326294 Automatic alarm systems GLIDDEN ELECTRIC CORP 26 May 1971 17183/71 Heading H4K  An alarm system, in which a motorized programming member dials a station to report the alarm condition, takes its power over the exchange line, loop disconnections effected for dialling by the programming member disconnecting the motor but the member being such that it coasts over each disconnection without motor power. Contacts 26 operate in response to fire, temperature, pressure, or illegal entry, and provides a loop which includes rectifier 40, wiper 64 of program disc 56, wiper 72, resistors 96, 98, back to rectifier 40 and the loop. In this circuit transistor 90 switches on to energize motor 60 from Zener diode 100 to drive disc 56. Wiper 70 in the first half turn of disc 56 impulses the loop to call a predetermined station. Switching on and off of the motor is effected by switching transistor 90 to reduce transients. In the second half turn of the program disc, wiper 72 is disconnected and wipers 70 and 68 come into circuit to power an audio oscillator 78 from Zener diodes 100, 104 in order to send a number of tone bursts characterizing the station. In this phase the motor is powered by a lower voltage over inductor 102 and Zener 104. The disc continues to cycle until a pulse of audio frequency from generator 117 is sent from the called station to activate timed amplifier 80 in order to operate latching relay 34 which puts the normal substation circuit back on line. This tone is gated at the end of a disc cycle by wiper 66, the disc coasting onwards from the point of disconnection. If reply at the called station 18 misses the start of the code tones, the called station hangs up and waits for the next cycle of the program disc. Zener diodes 54 and 122 limit voltages across rectifier 40 and oscillator 117.
